Analytical Methods Approved for Drinking Water Compliance
Monitoring of Inorganic Contaminants and Other Inorganic Constituents

Analysis for the following inorganic contaminants and constituents shall be conducted in accordance with the methods in the following
table, or their equivalent as determined by EPA. The methods are specified in 40 CFR 141.23 and Appendix A to Subpart C of Part 141.
The monitoring requirements are specified in 40 CFR 141.23, 141.41, 141.86 - 141.88, and 141.135.

The CFR is the legal reference for approved methods and takes precedence over this table. The table should accurately reflect the
analytical methods information published in 40 CFR 141.

Note: MDLs reported in Methods











200.7 and 200.9 were determined











using a 2X preconcentration step











during sample digestion; MDLs











determined by direct analysis (i.e.,











no sample digestion) will be











higher. For direct analysis of











cadmium by Method 200.7,











sample preconcentration using











pneumatic nebulization may be











required to achieve lower











detection limits.
